scatter plot. A scatter plot visually represents the relationship between two variables by displaying data points on a Cartesian plane, with one variable plotted along the x-axis and the other along the y-axis. This allows for easy identification of trends, correlations, or patterns between the sets of data. Additionally, a trend line can be added to further illustrate the relationship.
There is an inverse relationship between the datasets.
There is no correlation.
Regression.
The answer depends on what sort of variables the data are (qualitative, quantitative-discrete, quantitative-continuous are; the nature of the relationship (if any) between the data sets; how much information you wish the graph to convey and how much you would prefer to describe in the accompanying text.
bar graph
It is a positive relationship.
There is an inverse relationship between the datasets.
Comparing the relationship of two data sets is needed to see which of the two sets have more life distribution. Two data sets involve the use of simple plotting and contour plots.
There is no correlation.
